Watts Premier Water Filtration Booster Pump Kit for RO Reverse Osmosis Systems, Increases Water Flow, Includes Booster Pump, 110V Transformer, Tank Pressure Shutoff Switch, Fittings, Green Tubing

After reading the reviews I was nervous and skeptical about buying this but I really needed it so I took a chance, very glad I did.First, it's easy to install, if you can install your RO system, you can add this to it if you need more water pressure.The box I received from inside my Amazon outer box was already open, I wondered if I got somebody's returned item. I did not get the hose that was supposed to be included, it didn't matter since I had some extra hose. I got the pressure switch and the pump and the directions.The good news is, I installed it all in about 15 minutes complete. I plugged it in and it worked perfect. I did not need to adjust the limit switch, it works perfect. The pump is a surprisingly heavy thing. I had been planning to mount it on the wall under the kitchen sink but I mounted it on the floor instead. From the size and weight of the pump motor you might expect a lot of noise, once again, it's surprisingly quiet. We rarely can ever detect the pump is operating from the noise level, I'd say its downright quiet.We have an automatic ice maker in our refridgerator and needed the extra pressure to push water from our RO system under the kitchen sink to it. As soon as I plugged this pump in we began making ice, a lot of it.My RO system is an iSpring unit I bought here on Amazon. We are on a well system at our new home and the RO is NECESSARY but we did not realize we did not have enough water pressure (only 40psi). I contacted iSpring about adding a pump and it turned out to be a real hassle to add one to their RO system. I was depressed until I found this pump on Amazon, it seemed expensive but I was desperate to get our drinking water system online so we could stop buying bottled water. I bought one and I'm very glad, it's a great product. If you're at all handy you won't have any trouble installing this.One last good feature, the pump is made in America, no wonder it has a nice heavy quality feel.Wishing you all abundant clean drinking water.

I realize not everyone out there owns an RO (reverse osmosis) system and perhaps even fewer have one connected to their refrigerator. But if you do, you may want to consider this...We've owned an RO system since 1994, in fact we still have it. During that time we connected it to our old Maytag refrigerator's ice maker and water dispenser. Neither worked reliably or well. When the ice maker wasn't literally shooting ice cubes horizontally out the cup, it would continually freeze and malfunction (as ice makers do).Due to abnormally high frequency of repairs the only redeeming value we derived from the parade of service technicians was the opportunity to pick their brains. Time after time, each confirmed why the door mounted water dispenser was so agonizingly slow delivering water. It was primarily due to the reduced pressure from the RO system. Since the storage tank bladder and pressure were operating within spec this made sense.While having an RO system does provide a cleaner (no minerals) source of water, the downside is low water pressure plays havoc with ice-makers creating "ice dams" that block the H2O feeder tube. The internal ice-maker switch depends on a minimum amount of water pressure to engage. RO system pressure is typically around 7 PSI which dramatically less than city water pressure (about 30-60 PSI depending where you live). Inevitably the refrigerator water line (necessary for ice making) will freeze-up disabling the ice-maker and significantly reduce flow through the door H2O dispenser.Just about every refrigerator manufacturer recognizes this issue and addresses it within their respective owners manual. Our new Samsung is no exception. In fact, after contacting them and they highly recommend installing a water booster pump specifically for the reasons mentioned above.So after doing some research I found this Premier model on Amazon (coincidentally from the same manufacturer of our RO system) and ordered it for less than Premier's own website price.Since I installed it the same time we received our new Samsung I can't definitively state any measurable improvement. But compared with the previous Maytag, water flow is noticeably faster and dispensing pressure is higher (based on observation with pump turned on and off). I realize it may be too soon to report (almost 2 months) but best of all we haven't experienced any ice issues. While I can't unequivocally state this pump is making all the difference, I do feel confident it is helping prevent any recurrence of similar ice-maker issues... so far, so good.If you've ever replaced your RO system filters, have experience with basic tools (semi-skilled with home repairs) you can easily install this. If not, it shouldn't cost much to have someone do it, I was able to install ours in about 20 minutes. After depressurizing the RO system (same as during a filter change); mount the pump vertically to any wall (under the sink); splice one RO water line; re-pressurize the system; plug the pump into a standard 120VAC outlet (typically available under most sinks for dishwashers and disposals) and your good to go.As for the pump, it operates automatically (on-demand) and is exceptionally quiet, we never notice it working...

Extremely quiet, works as advertised. Remember that the allen wrench on the pressure sensor can adjust the pressure settings. turn clockwise to have it come on at lower pressures.Only complaint is that there should be 1/4 inch fittings and an adaptor for most standard installations. You will most likely have to go to a hardware store for more parts to finish this installation properly.Again, that's minor, but for 110 bucks a $1 worth of fittings would have been nice.

Had the typical problems with using water directly from RO system to feed my icemaker -- pressure to low etc.Gave up and used unfiltered water for years (plenty of pressure but ice cubes didn't taste great.)Found this and read the reviews -- I installed it to boost the pressure between the RO storage tank and the ICE maker.Took me about 2 hours to install -- now waiting for my first batch of ice cubes, but the fridge water dispenser works great so far. Pump is whisper quiet. Best part is saving about $60 with used like new.
